(o1. i-smj 15 Claims.

This invention relates to packaging nesta-ble strips or sticks and relates more particularly to` trough-shaped strips orsticks of frozen staples of the general type shown in United States-Patent No. 1,792,235, and to assemblies -of such sticks in packages.

Objects of the invention are to modify said sticks in a way to save staple material and to.'

allow the sticks to be more compactly packaged,

and to provide a very compact assembly of suchr sticks, thereby saving storage and shipping space and cost, and cost of containers for the assemf blies. 3

Additional objects of the invention are to effect simplicity and efliciency in such assemblies and packages and to provide an extremely-simple assembly of this kind which is economicalof space and material and easy and reliable in operation, andeconomicalto manufacture and asv semble.

.Still other objects of the invention will appear as the description proceeds;Y and while herein details of the invention are described in .the

speciication and some of the claims, the inven tion as described in some of the broader claimsis not limited to. these; and many and various; changes may be. made without departing fromy the scope of the invention as claimed in the' broader claims.

Ther inventive features for the accomplishmen of these and other objects yare shown herein'inconnection with a package which briefly stated,

includes a .plurality of vstaple stick assemblies,y

each .assembly comprisingL pairs of sticks nested together to form nests, the nests being arranged side-by-side and received within other sticks` thereby to provide compact assemblies.

In the accompanying drawing showing, by way of example one of many possible embodimentsv of the invention,

Fig. 1 shows a transverse sectional view on an enlarged scale taken through the end portion of a container of assemblies of the staple-sticks,

the staple sticks being. shown in end elevation;. Fig. 2 is an end elevation of one of the -assemfe blies shown on a still larger scale;

as in Fig. l

Fig. 4 is a perspective view of a stick asin Figs.

1 and 2.

My'improved staple-strip assembly comprises staple strips generally denoted by reference numeral 5*(Fig. 3) shown in a package comprising' an elongated rectangular container 6 of substantially square cross section and having a cover l, although cross sections other than square may be used. A plurality of layers oi. elongated frozen ,f staple assemblies 8 of substantially'square cross sectional outline are shown longitudinally. disposed in said container one above the other and engaging flat againstwalls ofthe container.v

Each assembly 8 (Fig..2) .comprises a pair'lof..

inner staple nests I0, II, each nest comprisinga pair of parallel trough-shaped frozen-staple:

sticks I2, i3, each stick comprising opposite sidewall or leg parts I4, I.5,1 (Fig. 3). and abridgepart I6, the leg parts I4, I5 of one stick I2 l:being placed iiat against inner and outer faces of the respec: tive leg parts I5, I4 of the other stick I3 with,

their free edge portions I8 adjacent to the plane of the bridge part I6 of such. other stick.1

'Said nests I0,` II are placed withthe outer Y face of one Ibridge part I6 of one nest I0 engaged againstthe outer faceof a-bridge vpart I6 of the nest Il, leaving. pairs of facesof leg parts I5 4of said pairs of nests exposed and adjacent substantially inthe. same plane.

Staple vsticks 20 and 2l respectively embrace,

said pairs of adjacent faces I5 with the inner.

face of the bridge part I6 of such stick 20 or 2 I "against said pair of faces I5, and vthe inner iace of the leg parts I4, I5 against outer bridge parts I6 of said pair of nests IIL, I I.

Staple sticksa (Figr) similar son,` the staple sticka 1is not wide enough to embrace two nests lila, IIa., as shown by the arcf ISR having the bridge'portion I6 of Fig. 3 as its radius.; Thus it is notpossib-le to nest the `sticks Saas in Fig. 2

By making the and are otherwise practically vfullyas veilicientas before, and may be usedv in the st apling ma?. chines now in use and on the market. In addik row, it is possible toassernble them as in Figs., 1 and 2,which is quite an improvement over-the best possiblemethod of assembling the sticks f5 a.

thus' Aeiecting saving in shipping andf storing.

costs and in metal without vanygdecrease in efficienc-y. Also` the assembly1method-vcit-Fig. 3` requires about 30 rto 10% more cardboard, d epending on the lengthjof the'boxior container.

The invention claimed is: 1. A staple-strip assembly comprising a pair of tothoseheretofore on the markethave theirleg portions Illa, Iaslightly wider relativeto their bridge portions I6 than are the l eg po r tions I4, I5 to the Ibridge portion I6 of the jsticks .5. r Forfthis realeg portions I4,` I5 about threef. sixty-fourths of aninch narrower relative tothe wide portion I6 of the st ick, some staple wire is saved, but the staples are less likelyto bend when passing through many thicknesses of tough paper of inner staple nests comprising a pair of parallel trough-shaped frozen-staple sticks, eachu stick comprising opposite leg parts and a bridge part, the leg parts of one stick being placed fiat against outer and inner faces of the` respective leg parts of the other; said nests being placed with lthe outer face of one bridge part of one nest engaged a-gainst the outer face of a bridge part of the other nest, leaving pairs of faces of. leg parts of said pair of nests adjacent; and a staple stick. embracing each of said pairs of adjacent faces with the inner face of the bridge part of suchstick against said pairs of faces.

3. A staple strip assembly comprising a plurality of staple nestsyand a staple stick embracing said nests.

5'. A trough-shapedl staple stick, comprising opposite leg parts and a bridge part, each wall part being. less than` half the width of the bridge part, whereby a number of said sticks may be assembled into a staple stick assembly comprising a pai-r of inner staple nests,1 the leg parts of one stick of each nest being placed flat against leg parts of the other stick of suoliv nest; said nests being placed` side-by-side with leg parts of said pair of nests adjacent in the same plane, and a staple stick embracing eachcf the pairs of ad,- jacent leg parts,

6. An assembly of members, each member comprising opposite side wallparts, said assembly comprising a plurality of nests of members; and y a member embracing said nests.
